IMPRO/VEMENT IN SIFTERS.

Specification forming part of Letters Patent No. 209,710. dated November5, 1878; application iiled October 10, 1878.

To all whom it may concern:

Beit known that I, CHARLES O. BECK, of Pittsfield, county of Berkshire,State of Massachusetts, have invented an Improvement in Sitters, ofwhich the following description, in connection with the drawing forminga part thereof, is a specification.

This invention relates to an improvement in ash-sifters; and theinvention consists, chiefly, iu an inclosingcase and hopper combinedwith a rotating conical sieve, one end of which is prolonged axially toserve as one of the journals for the sieve, and also-as thedischarge-outlet, the inclosing-case being adapted to be attachedto abarrel, box, or other cover.

, Figure l represents, in side elevation, one

' of my improved ash-sitters, the cover to which it is attached beingplaced upon a barrel, whichis to receive the ashes. Fig. 2is alongitudinal section taken through the sifter; Fig. 3, a cross-sectionthrough the hopper on the line ma. Fig. 4 shows one of the castmetalgrates of which, in practice, the rotating sieve will be formed.

The inclosing-case c and hopper b, attached at one end thereof, andprovided with a cover, c, are made preferably of sheet or galvanizediron; but the ends ofthe case may be of castiron.

Ihe conical sieve d, provided with ysuitable passages for' thelire-ashes, has at its larger end a head, c, through which is made auopening, f, (shown in black,) which, at each revolution of thesieve, isbrought opposite the lower inclined bottom of the hopper, as is shown inFigs. 2 and 3, to then receive coal and ashes from the hopper, the sizeof the said opening f graduating the quantity of ashes which can enterthe sieve at each rotation.

n Attached to the head c, and having a bearwhich the sieve 1s rotated. Y

At the small end of the conical sieve, and made asan'aXial prolongationthereof, is a tubular spout, h, which serves as a journal for the smallend lof the sieve, and also as the discharge openingV or spout, throughwhich the coal, the line ashes having'been removed from it through thepassages `2, of any suitable ing in the hopper-case b, is a handle, g,byv

shape, is discharged into a coal-hod, t', or other suitable receptacle.

Upon the inclosing-case is secured a hodholder, j, and the case is inthis instance shown as attached, as it preferably will be, to a iangedcover, k, which may be readily applied to the open end of a barrel, l,or box to receive the fire-ashes.

In practice the sieve d will be composed of a number of cast-metalscreens, as at m, Fig. 4, which will be secured to suitable flanges orportions of the head c and of the deliveringspout h. t

By means of this sifter ashes may be easily and quickly sifted, the coalseparatedtherefrom, and fed into a hod without the discharge of ashes inthe air.

1t will be noticed .that the tubular projection h is not a conicalcontinuation ot' the conical sieve, but is a cylindrical apeXialtermination thereof'. By this construction the sieve has a journal ofuniformi diameter throughout, so that it may turn in its bearing easily,whereas it' it were of cone shape the rotary motion and Weight of thesieve would tend to crowd it into its bearings and make it work hard.

My sieve is further provided with an annular shoulder, abutting againstthe casing adjacent to the extensionh, which serves to preventlongitudinal displacement thereof.

I claim- 1. The conical sieve, terminating at its apex' in a shoulderedtubular cylindrical axial eX- tension, h,y substantially as and for thepurpose described. Y

2. The inclosing-case a andrhopper, combined with the rotating conicalsieve, having .a head, e, provided vvith'an opening, f, to admit ashesinto the sieve for but a portion of each rotation of the sieve,substantially as described.

In testimony whereof I have signed myname to this specification in thepresence of two subscribing witnesses.
